[amibroker] Re: Calculating No of Bars since Start of Previous Month

["Mike" <sfclimbers@xxxxxxxxx>]

Here is a zero based example (i.e. does not include current bar in the total). Add one to the result if you want to count the current bar.

Months = Month();
ChangeOfMonth = (Months != Ref(Months, -1));
Indices = BarIndex();

Bars = Indices - ValueWhen(ChangeOfMonth, Indices, 2);

Plot(Bars, "Bars", colorBlue, styleStaircase);
_N(Title = StrFormat("{{DATE}} {{VALUES}}"));
